The PC fails to start unless the power supply connection is interrupted and then reconnected.
I recently turned on my PC and noticed it didn’t respond when I pressed the power button. All connections and outlet power seemed fine. The motherboard lights were on but didn’t react. After several attempts, I found that briefly turning the PSU circuit on and off caused it to start normally afterward. RAM and CPU performance were unaffected. The motherboard appears to have working components, yet the issue persists. I’m unsure if a faulty power delivery unit or another hidden problem is at play. Since I can’t afford a new motherboard right now, any suggestions would be greatly appreciated.
It can be aglitch in the motherboard BIOS. Did you try flashing another BIOS version ? If you are not running the latest BIOS, try updateing. If you are running the latest, try reverting back a version or two. There is also a slight change that your CPU has a bit of degradation (13th gen Intel...) and that causes the issue. But IMHO the motherboard and BIOS are more likely the cause than the CPU. Good luck !
This shows the power source is activating one of its safety features. If a protection such as short circuit trips, the unit will cut off power and require manual reset before it can restart. This occurs in standby mode. While in standby, the PSU connects to a separate 5VSB line that supplies power to the motherboard and USB devices. Since you've switched to another PSU without fixing the issue, the problem likely lies elsewhere—possibly with a device or motherboard during standby. Provide a list of all connected items: power supply components (including fans, RGB parts), peripherals, and any USB devices. Try disconnecting them one by one to determine if the fault remains. For testing, disassemble the system and test only essential parts like the motherboard, CPU, and RAM. If the issue persists without additional connections, the hardware may be faulty.
